Ace-mode fails to highlight regex-splitting

[vendethiel]

Not sure how it should do it (is it possible with regexps without ugly hacks ?) but ace-mode fails to highlight a / / /

The vim-coco plugin also has trouble with regex highlighting, FWIW. The ambiguities with division and regexes starting with spaces are really hard to account for in simple syntax highlighting engines.

The <expr> / <regex literal> as sugar for split does tend to create most of the ambiguities that break syntax highlighters. Maybe somehow special-case the engines in ace-mode and vim-coco to handle that better.

# tricky :
breadcrumbs = window.location.pathname / \/

do we consider spaces should be \s ?
